For vehicles with steering wheel buttons, if you
deactivate ATTENTION ASSIST, the system is
automatically re-activated when you start the
engine. The system sensitivity then corresponds
to the last selection activated – standard or sen-
sitive.
If you switch off ATTENTION ASSIST in a vehicle
without steering wheel buttons, the system
remains switched off even after you start the
engine. The status of the system after switching
on the engine always corresponds to the status
last selected.

On long journeys, take regular breaks in good
time to allow yourself to rest. If you do not take
a break and ATTENTION ASSIST continues to
detect increasing lapses in concentration, you
will be warned again after 15 minutes at the
earliest. This will only happen if ATTEN-
TION ASSIST still detects typical indicators of
fatigue or increasing lapses in concentration.

PARKTRONIC

General notes
PARKTRONIC is an electronic parking aid. The
system is equipped with ultrasonic sensors in
the front and rear bumpers to monitor the area
around your vehicle. PARKTRONIC indicates vis-
ually and audibly the distance between your
vehicle and an object.
Your vehicle features two separate sound emit-
ters with different frequencies for the warning
tones. The warning ranges in front of and behind
the vehicle are indicated by different warning
tones.

PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). PARKTRONIC is reactivated

Important safety notes
PARKTRONIC is only an aid. It cannot replace
your own awareness of the immediate surround-
ings. You are responsible for safe maneuvering,
parking and pulling away. When maneuvering,
parking and pulling away, make sure that there

Pay particular attention to obstacles above
or below the sensors when parking, such as
flower pots or trailer towbars. PARKTRONIC
does not recognize such objects when they
are in the immediate vicinity of the vehicle.
You could damage the vehicle or objects.
PARKTRONIC can suffer interference from:
ultrasonic sources such as a truck's

the bumper, not the ball coupling.
